the 'reverse record' for the IP address.. like a normal record looks
like

www.foo.com. 	IN	A	1.2.3.4

whereas the PTR records are the opposite, they match each IP address to
a host

4	IN	PTR	www.foo.com.

would match '4' in this case of the 1.2.3 class C to www.foo.com it gets
infinantly more difficult to understand as you get farther away from a
single class C

umm.. anyways, if you didnt have a PTR record for mail2.alphashop.com it
wouldn't reverse resolve, which is something a lot of mail servers
require other mail servers to do these days to protect against
spam(although I've never heard of MSN trying to protect its customers
from spam before..)

at any rate, looks like its good now. is the customer having issues
still?
